(54)	Trigger sprayer having a two-piece housing construction

(57) A trigger sprayer apparatus is comprised of a sprayer housing and a vent housing that are formed independently of each other and are then assembled together. By providing a separate sprayer housing and vent housing, the sprayer apparatus may be produced in a manner that significantly reduces the occurrence of deformations or imperfections in the component parts of the apparatus. Moulding the sprayer housing and vent housing separately enables the cylindrical interior surface of the vent chamber to be moulded more accurately. Less material is needed for each component, and shrinkage on cooling is reduced.
